Application filed. January 28, 1915. Serial No. 4,849.

1'0 all whom it may concern: 7

Be it known that I, ERNEST H. ARNOLD, subject of the King of England, residing at Cleveland, in thecounty of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Pulleys, of which the following is a specification.

This invention relates to pulleys and has for its object to provide an improved pulley block comprising a metal body which supports the roller, the sides and the lower end of the body being formed in a single piece, and the lower end being closed, the upper end which receives the swivel being closed by means of a screw cap which looks the sides together. The closed lower end is particularly desirable as it holds the sides together and gives a neat appearance.

All parts of the block can ,be made of sheet metal, and the body is formed of a single stamping, bent to shape as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of the pulley. Fig. 2 is a longitudinal section. Fig. 3 is a plan of the blank from which the body is made.

Fig. 4 isa section of the cap.

The body of the pulley is preferably made of sheet metal stamped in the form shown in Fig. 3, comprising the two parts 6 which form th sides, a connecting neck orf-part 7 which forms the lower end of the block, and two half necks 8 which are dished or bent to semi-circular form. This body after it is shaped in the blank is bent or folded to bring the two sides 6 opposite each other and to join the half necks 8 at the top, the pulley wheel 9, which may be of any suitable construction, being inserted and mounted on the pin 10, the heads of which are riveted to the sides, the pin passing through holes 11 in the sides.

The neck formed by the two parts 8 is threaded externally to receive the screw cap or collar 12, which may also be stamped from sheet metal, and is internally threaded. This cap has a hole 13 to receive the stem of the swivel eye 14 which is headed within the cap. The cap is also formed with two ears or lugs 15 at opposite sides of its lower edge, and after the cap is screwed into place, these lugs are struck or bent in under the edges of the neck portions 8, and between the upper ends of the sides 6, locking the cap in place and preventingthe same from becoming practically as strong as a solid'or cast.

metal block.

What I claim as new is:

1. A pulley. comprising a body having opposite sides and parts joined at. the top to form a neck, acap extending around said neck and holding said parts together, an eye connected to said cap, andawheel between the sides. I V

2. A pulley comprising abody having opposite sides connected at their lower ends and joined at their upper ends to form a neck, a cap fitting on said neck,'a hanging device connected to the cap, and a wheel between the sides. I I

3. A pulley comprising a, body made of a sheet metal blank bent to form opposite sides, and an integral connecting part at the lower end thereof, and neckparts at the upper end thereof, a cap fitting on said neck, an eye swiveled to the cap, and a wheel between the sides.

4. A pulley comprisingabody having two.

sides each having a'threaded neck part at the top, a cap screwed on said neck, a swivel eye connected to the cap, and a wheel journaled between the sides.

5. A pulley comprising a body having two sides each having aneck part at "the top, a cap fitting around said neck and having lugs engaging betweenthe sides. and under said neck parts, and a wheel journaled between the sides. p

6. A pulley comprising a sheet metal blank bent to form two sides, a connection between the lower ends thereof and two half In testimony whereof, I do affix my signaneck parts joined at the top, a cap screwed ture in presence of two witnesses.

on said neck parts and having lugs bent ERNEST H. ARNOLD. thereunder, an eye swiveled to said cap, a Witnesses:

5 pin between the sides, and a wheel on said JOHN A. BOMMHARDT,
